had a lemma as short as 7 mm, in most the}' are 8 or 9; HiTCHCOCK has /■ — 8. 

 The length of the glumes varies even more, and so does the awn (see Table II). 

 We could perhaps group the material in three lots: i) "typical" neesiana: empty 

 glumes II — 13 and 10 — 12 min, respectively, body of lemma 7 — 8.5, awn as a 

 rule not over 50 mm; 2) empty glumes 13 — 15 and 11 — 14, body of lemma 

 ■8 — 10, awn attaining 60 or 65 mm; 3) spikelets distinctly larger, empty glumes 

 16 — 22 and 14 — 20, body of lemma 9 — ^11. awn to 70, 80 or 90 mm, or even 

 longer. Lot 2 would correspond to var. fernandeziana, but among plants from 

 the islands Bertero 800 p. p. and Skottsb. 447 belong to lot i, and Philippi 

 {coll. 1864) to lot 3. Trinius & Ruprecht's statement "foliis planiusculis cum 

 nodis glabris" does not hold good; all according to the conditions the blade is 

 ilat or convolute, and as a rule hirsute at least on inside, and the nodes are 

 more or less hairy. They are, perhaps, almost glabrous in the type specimen, 

 labelled "Juan Fernandez, Prescott". I have never heard of him as a collector 

 in these islands, and he is not in JOHOW's list. My specimens were identified
